En los nuevos B3 no se puede anular el star&stop, si no cambias esa batería no actúa el star &stop ?? Sirve como forma de “anular” el star & stop ?? o la pequeña batería interfiere en más elementos y es necesario su cambio ? Gracias

You Need to charge the battery only. No replacement necessary. It shows up on your message because you are not driving enough. It it Will be noticed early when the start/stop function vill stop working. Charge the battery now and then and you are good to go.
